The OP is a report from a committee of leading experts, formed by the National Academies, tasked with reviewing "the critical facilities, workforce, and technology needed to achieve NASA’s long-term strategic goals and mission objectives".
It's interesting not only for the insights into NASA as an organization and the critique, but also for two appendices providing updated reviews and prospects of in-progress long term missions and of R&D into critical tech such as planetary entry, decent and landing; planetary ascent (take-off from other planets); in-space propulsion; habitats outside Earth; and in-situ resource utilization on Mars (i.e., utilzing local materials instead of bringing them).
(And also an interesting section on transitioning from engineer to engineering manager.)
